Rules to remember while creating MVC - Controller's action method

1. Action methods must be public
2. Action methods can't be static
3. Action methods can be overloaded
4. Action methods can't be overridden

6. Action method parameters can't be 'ref' or 'out'.
7. Actions can't be extension methods.
7. All actions are invoked by 'Get' request.
